Russ Roberts gives a brief review of The Visitor, in which the main character is an economist. I have been trying to think of any major characters from movies, books, tv, etc that has a major character who is an economist.
The best I can recall is in Robert Ludlum's Jason Bourne series. In the books, Jason Bourne's wife is a famous economist. For the movies, they changed the character from an economist to a gypsy.
Any better ones out there?
